White spaces are disallowed:

SampleSheetGenerator/samplesheet.py

Line 463 in f4e6fc1

self.sample_name_pattern = re.compile(r"^[0-9A-Za-z_-]+$")

whitespaces could be cleaned as the data is ingested

yes, but it's not how it looks like in the singlecellsheet class. At least I count find that it anywhere takes care of white spaces, and I've seen that white spaces poped up in the CTG_samplesheet if there were any

sure, it could be added in the validation function for that too.
